Title: Means for the obtaining of continuous movements in electrically-driven typewriting and similar office machines
IPC: B41J25/02
Filed: 1959-05-04
Abstract: 870,217. Typewriters. TRIUMPH WERKE NURNBERG A.G. May 4, 1959 [June 4, 1958], No. 15146/59. Class 100(4) A repeat action mechanism for an electrically driven typewriter or like machine for effecting, e.g. continuous line, letter or back-spacing comprises a carrier 1 pivotally supporting a spring biased eccentric carrying actuator 4, normally held away from a power roller 13 by a locking pawl 6, and a holding pawl 5 controlled by a shift rod 40 associated with the line &c. spacing mechanism which restrains the actuator 4 at the end of the advance of shift rod 40 but releases the actuator 4 upon retraction of the rod 40 whereby the actuator 4 may again operate unless the locking pawl 6 has been made effective by release of its key. Initial operation of a key causes a slide 22 to pivot the locking pawl 6 so the actuator 4 swings to allow the eccentric 9 to engage roller 13. This eventually pulls arm 27 and through linkages 31-39 moves the shift rod 40 upwardly to effect, e.g. line-spacing. The rod is retained by a slide 43 until line-spacing is carried out. The shift rod 40 also, by means of linkage 44-46 causes the holding pawl 5 to retain the actuator 4 against further action, as by this time, it has returned to initial position. If the operating key has been released, the slide 22 allows the locking pawl to retain the actuator, but if not, then the holding pawl is ineffective and a further line &c. action occurs.
